Definitions

  • the present invention relates to a vehicles dynamic navigation system.
  • the main function of vehicle navigation systems is to provide the driver of the vehicle with a sequence of graphical and/or vocal information regarding a route to follow to reach a desired and selectable destination in an optimal manner.
  • These systems are essentially composed of a receiver unit for radio signals originating from satellites forming part of a satellite positioning system, such as the GPS system for example, or from broadcast devices located in the area around the vehicle, a processing unit, which calculates the position of the vehicle based on the signal received from the satellite system, and a user interface that has the main task of providing the driver of the vehicle with graphical and/or vocal route information.
  • the user interface is used in the navigation system for entering the necessary data for calculating the route.
  • navigation systems of the onboard type in which calculation of the route requested by the user is carried out directly onboard the vehicle by a specially provided processing unit
  • navigation systems of the off-board type in which calculation of the route requested by the user is carried out externally to the vehicle.
  • calculation of the route between the current position of the vehicle and the destination that the user wishes to reach is carried out by an operations centre in communication with the vehicle and transmitted by the centre to the navigation system integrated on board the vehicle, which receives the calculated data from the operations centre and provides the driver with the graphical and/or vocal instructions on the route to follow.
  • the main advantage of off-board navigation systems is that of achieving a fundamental simplification of the navigation system integrated on board the vehicle, as the processing unit of the onboard navigation system limits itself to calculating the position of the vehicle, but does not implement the algorithms necessary to calculate routes, nor does it need all of the data storage units necessary for storing cartographic maps.
  • Another advantage of off-board navigation systems consists in that the updating of information of a geographic nature used for calculating the routes requested by the user is carried out with an opportune frequency directly by the operations centre, relieving the user of this task. This guarantees the supply of an ever-efficient service, the reliability of which is not affected by possible errors due to geographic information that has not been updated by the user.
  • vehicle navigation systems constitute a commercial product in strong expansion, due both to the need of car manufacturers to differentiate themselves in vehicle ranges equipped with technological systems increasingly on the cutting-edge, and because of the new road mobility needs of motorists who drive in increasingly complex scenarios and need and an ever-increasing amount of varied information.
  • Dynamic navigation systems are also able to monitor the route driven along by the user in relation to the road conditions and to provide the user with an alternative route in cases where events arise that compromise the road conditions of the route being taken, such as accidents or heavy traffic for example.
  • off-board dynamic navigation systems oblige the user to delay commencing navigation and to wait until information regarding the requested route is received from the operations centre.
  • the main drawback of onboard dynamic navigation systems is mainly caused by the large amount of data concerning the road conditions of the road network, which must be periodically provided to the onboard system and which the latter must process.
  • the transmission of such a large amount of data requires the constant availability of rather high bandwidth, while its processing by the onboard system requires the use of high-performance processing and data storage units, which are generally rather expensive and thus condition the overall cost of the vehicle.
  • EP-A-1 186 865 discloses a motor vehicle navigation system that receives route information from a central unit, wherein a vehicle route between an instantaneous location and a destination is calculated, such that data about the instantaneous location and the destination are determined in the vehicle as data about the current route, traffic information data are delivered from a central traffic information data memory to a traffic network, the delivered traffic information data are used to calculate the route in the traffic network between the instantaneous location and the destination location, the data of the calculated route and the data about the current route are made available to the driver, characterized in that the data about the current route are transmitted from the vehicle to the central traffic information data memory, and, as the response to the transmission of data, traffic information data are delivered about the current route.
  • EP-A-O 845 658 discloses a dynamic route guidance apparatus, wherein a vehicle transmits destination to a control center, and the control center obtains an optimum route in consideration of current traffic conditions and notifies the vehicle of the route.
  • the vehicle In order to avoid detouring, the vehicle itself searches a route to the destination, and transmits destination data on a link to the control center. The link is located nearest to the destination among all UTMS links on the searched route, the UTMS links being controlled by the control center.
  • the control center calculates a recommended route which includes the notified link as a tailing link, and informs the vehicle of the route. The vehicle combines the searched route and the informed route into a final guiding route.
  • JP 07 190794 A discloses an on-vehicle route acquisition device adapted to provide route information optimum for a vehicle travel condition by evaluating a route obtained through an on-vehicle communication means and making judgement about the appropriateness of the route.
  • destination data and a calculation request signal are inputted at a process and when a vehicle enters the service area of a beacon on a road during a travel, a destination and the like transmission section sends destination coordinates to the beacon via a process. Also, the beacon sends back a link train or the like leading to a terminal link.
  • a controller makes judgement about whether route information from the beacon or route calculated on a vehicle should be adopted.
  • a rectilinear distance between a receiving position and a destination is calculated, and when the distance is shorter than the prescribed distance, a receiving route is judged not to be appropriate.
  • a previously obtained optimum route exists, judgement is made as to whether the vehicle is travelling along the route.
  • a route between a current position and the destination is calculated for use as an optimum route.
  • this route is used as an optimum route. If not included, guidance is continued following the previously obtained optimum route.
